PentestingJun 10, 2026

Your Automated Pentest Looks Clean. Here’s What It Misses

A spotless pentest report can feel reassuring. It can also be misleading. Run automated pentesting a few cycles in a row and the “new” findings taper off. By the third or fourth pass, the report looks steady. It’s easy for “stable” to read as “secure.” Often, it isn’t. The pace slows. The risk stays. That […]

Claude Fable 5 launches with cyber safeguards; Mythos 5 kept for vetted defenders

Anthropic released Claude Fable 5 on June 9. It’s the company’s most capable model to date and generally available. There’s a twist: Anthropic is shipping one underlying model in two forms, separated by a layer of safety classifiers. Fable 5 is the public release. Claude Mythos 5—functionally the same model with cyber safeguards lifted—remains restricted […]

Proto6: Six protobuf.js flaws expose Node.js apps to RCE and DoS

Six vulnerabilities in protobuf.js—the JavaScript/TypeScript implementation of Protocol Buffers (Protobuf)—can lead to remote code execution (RCE) and denial of service (DoS) in Node.js environments. Cyera’s research team collectively codenamed the issues Proto6. If you work with services that serialize or deserialize Protobuf, this matters. Protobuf is a widely used, open-source way to encode structured data. […]

Meta will use off‑site business data to personalize Feed and AI

Meta said on Tuesday that it will start using information shared by other businesses to personalize more than ads. That same off‑site activity will shape what you see in your Feed and how its AI chatbot responds. What’s changing Meta already uses off‑site activity — like games you play or purchases you make on other […]

Russia-Aligned Groups Still Exploit WinRAR Flaw to Plant Stealers in Ukraine

Two Russia-aligned campaigns are still abusing a known WinRAR vulnerability to target organizations in Ukraine, nearly a year after patches became available. Trend Micro links the activity to Earth Dahu (also known as Gamaredon) and SHADOW-EARTH-066 (also tracked as UAC-0226). The shared entry point is CVE-2025-8088, a path traversal issue that lets attackers write files […]

The Hidden Risk in Modern Networks: Work Between Tools

Security teams see more than ever. Bigger tech stacks. Better coverage. More AI and automation to handle routine work. Yet the same problems linger: outages that last hours, lost revenue, slow MTTR, misconfigurations, and human error that trigger major incidents. Even with AI, teams feel stretched and exhausted. The issue isn’t detection or the tools […]

FROST: A Browser‑Based SSD Timing Attack That Reveals Sites and Apps

A malicious page can learn which websites you open and which desktop apps you launch by measuring your SSD’s timing—using only JavaScript. The technique, called FROST, runs inside the browser sandbox. No extensions. No native code. No permission prompt. You load the page, leave the tab open, and its code quietly measures drive contention in […]

Check Point VPN IKEv1 Flaw Exploited to Bypass Passwords

A critical flaw in Check Point’s Remote Access VPN and Mobile Access, when configured to use the deprecated IKEv1 key exchange protocol, is being actively exploited. The issue, tracked as CVE-2026-50751 (CVSS 9.3), stems from a logic flow weakness in certificate validation. In practice, it lets an unauthenticated remote attacker establish a remote access VPN […]

SNAP: Private Agent Payments on Solana with Zero‑Knowledge Proofs

AI agents are starting to act like businesses. They pay for APIs, buy data, settle trades, and manage compute on their own. Put those payments on a public chain, though, and a hard problem shows up: surveillance. When every payment is public, an agent’s financial graph is exposed. Who it pays. How much. When. That […]

Stop uploading your app manually—let Fastlane handle it

Every mobile dev has a release ritual. Mine took 30–40 minutes a week and didn’t help users at all. If you ship to both stores, you know the routine. Open Play Console, create a release, upload the AAB, write notes, submit for review. Then repeat in App Store Connect—now add Xcode archives, signing certificates, and […]

Cut Agent Token Usage by 89%—Without Touching the Agent

Every time your agent calls an LLM, it quietly resends the full conversation history. Turn 20 includes turns 1–19. Turn 50 includes turns 1–49. It’s invisible, automatic, and expensive. I noticed this while building Trooper—a Go proxy that sits between agents and LLMs. Watching token counts climb over a long debugging session made it clear: […]

200 Accounts: Wiring the Fediverse Registration Coordinator to Disk

There was a clear goal: reach 200 accounts in the Fediverse expansion. The coordinator existed. The target was set. But nothing wrote results to disk. That kind of gap is frustrating. You can call register_one, get a valid token back, and then… the process drops it on the floor and exits. No persistence. No registry […]
